IMPROVEMENT IN COOKlNG-STOVES.

Specification forming part of Letters Patent N0. 206,252, dated July 23, 1878; application filed January 9, 1878.

To all whom it may concern:

Be it known that I, JAMES A. LAWSON, of the city of Troy, county of Rensse'laer, and State of New York, have invented a new Improvement in CookingStoves, of which the following is a specification:

The nature of my invention consists in the manner of arranging and constructing a fuelsupply aperture and covers to close the same, as applied to cooking-stoves, the object of which is to produce a large and convenient opening for putting in the fuel at the top of the stove and over the fire, so that when wood is used the sticks may be put in on their sides, instead of being forced in at the usual end fire-door, and the fuel-supply aperture may be easily opened and closed.

My invention consists in making a fuel-supply aperture in the top at the front and over the fire-chamber, and combining therewith two horizontally-swinging covers with the latter, each swinging from their line of union with the top at their pivoted corners, separating as they swing out to uncover the fuel-supply aperture, and approaching each other to cover the same by contact, and so arranged that each cover may be operated independently of the other, and so as to uncover a part of the fuel-aperture when desired, or the whole of it by both.

My invention also consists in combining, with a fuel-feedin g aperture and two horizontally-swingingcovers,aremovable center-piece rest, so that when the covers are swung out the center-piece rest and centerpiece may be removed and the whole area of the fire-chamber top opened when it is desired to insert a very large stick of wood, which 1s too knotty to split, and which cannot be passed 1n at the other aperture.

My invention also consists in combining, 111 a cooking-stove,the fuel-supply aperture formed in the top at the front, and provided with the two horizontallyswinging covers, and the doors opening into the front of the fire-chamber beneath the top for the insertion of broiling apparatus.

My invention also consists of combining, in a cookin g-stove, the fuel-supply aperture formed in the top at the front with the horizontallyswinging covers and the removable centerpiece rest, together with the front doors beneath the top, and opening into the fire-chamber for the insertion of a broiling apparatus.

In the accompanying drawings there are six figures illustrating my invention, and these are shown in connection with the parts of a cooking-stove to which they relate, and in all the drawings the same letters are applied to designate the same parts.

Figure 1 exhibits, in perspective, a section of a cooking-stove, showing my invention with the fuel-aperture formed in the top and the pivoted swinging covers partly opened. This illustration also shows the removable centerpiece rest and center-piece. Fig. 2 exhibits the section of a stove in perspective, with the pivoted swinging covers closed and in contact upon their closing edges; also the doors in the front below the top opening into the fire chamber for the insertion of a broiling apparatus. Fig. 3 shows a vertical section of the part of a stove containing my invention, and as taken on the line V V of Fig. 2. Fig. 4 exhibits a top view of the turn-table plate formed in the stove-top, and as having an aperture, through which the feathered pivot attached to each of the covers passes, and on which they swing horizontally. Fig. 5 shows a section of the cover and the pivot, as well as the circular turn-plate formed in the top and below the plane of the latter, taken vertically on the line H Z of Fig. 2. Fig. 6 exhibits a section of the feathered pivot, the cover to which the latter is attached, the semicircular turn-table formed in the top, all taken on the line Y Y vertically of Fig. 2.

The several parts of the stove are desi nated by letter-reference as follows: The fuelaperture is shown at A as formed upon the top and front, and as extending across the same. The horizontally-swinging and pivoted covers are designated at D D, and as having semicircular turn-plate corners at H H. The letter M is placed to denote the fire-chamber, S the stove-top, and S S a semicircular turn-table section formed in the latter, and in a lower plane than the rest of the top, and which coincides in form with that of the turnplate corners H H, formed in the covers. The removable center-piece rest is designated at It as forming a striking-face for the closed covers and a support at the front for the usual center-piece (J, placed between the boilerholes. The letters 13 B are used to denote the doors beneath the top, at the front, which open into the fire-chamber below the stovetop, to insert a broiling apparatus. IV V dosignate the exterior perpendicular walls of the stove; G, the grate; K, the rear wall of the fire-chamber. At L is shown the aperture in the turn-table plate. I designates the pivot and feather, and I? the pivot with the feather turned back. The removable center piece rest has a lip formed upon each edge at the end, and this rests upon a corresponding flan gc formed upon the under side of the top. A dowel or pin attached to therest passes through a hole made in the flange formed on the lower edge of the top, as shown at (Z (Z of Fig. 1, from which means of support the center-piece rest may be easily lifted out and removed.

\Vith the fuel-aperture designated at A, and as extending across the front, a large fuelsupply opening is produced, through which wood can be easily fed into the fire, and when combined, in construction, with the two horizontally-swinging covers, it is easily opened and closed, and the fuel can be much more easily inserted than when forced through the usual end door, which opens into the firechamber.

'When it is desired to burn knotty pieces of wood, and such as cannot be split, and are too large to be put into the fire-ehamber through the aperture A, then the removable centerpiece rest B may be taken out, also the center-piece G, which it supports, which will uncover the whole top of the fire-chamber, so that pieces-of wood as large as the fire-chamber may be inserted-a great convenience where wood is burned and it is desired to keep up a slow fire through the night without repleir ishin There being two l1orizontally-swinging pivoted covers, a part of the fuel-aperture can be opened by swinging out one of them, or the whole area of it by both, and thus a very large fuelsupply aperture can be utilized without the necessity of operating one large cover, which would be heavy and cumbersome, and which would project too far from the stove to be convenient.

I am well aware that a fuel-supply aperture has been formed in the top and at the front of a cooking-stove designed to burn coal, which was closed by a single swinging cover; but a single swinging cover must necessarily be limited to an opening of only a portion of the top over the fire-chamber, and it could not be used where the whole length of the fire-chamber was uncovered without great i11- convenience. In fact, ahorizontally-swinging cover made in a single piece, and extending across the whole front, would so warp, from its length and the unequal expansion to which it would be exposed, as to become inoperative and useless. *ly the use of two swinging covers, however, this difliculty is avoided, and a fuel-supply aperture utilized which extends across the whole front of the top, if desired, and by means of which a removable centerpiece rest is made available, so that the whole area of the top over the fire-chamber may be uncovered, and large knotty pieces of wood may be inserted and burned, which could not be used were the fuel supply aperture restricted to the size necessary to make a single horizontally-swimging cover applicable.

'XVhile I have shown the covers as arranged to swingby means of afeathered pivot, and with the pivot-aperture formed in the semicircular table-plate, the covers may be arranged to swing horizontally to open and close by any pivoting means, provided the semicircular turn-plate is formed in the cover and the coinciding table-plate in the top.

I am well aware that two llOllZOlltilllY-SWIU gin g covers have been employed to form a hearth-plate, and hinged to the front stovewall, arranged to uncover a broiling apparatus; but they were not formed in and pivoted to the usual boiler-hole top, and so as to form, when closed, inparallel continuity, a part of the stove-top.

I am also aware thatremovablc center-pieces are'not new, the difference existing-between my removable center-piece rest and the usual center-piece being that the rest which supports the center-piece at the front is usually made fixed and cast with and as a part of the top, while in my arrangement of combined parts to open the whole area of the fireehamber top, the rest may be taken out as well as the center-piece.

Having thus described my invention, what I claim, and desire to secure by Letters Pat cut, is

1. In a cooking stove or range, the combination of the fuel-supply aperture A, formed in the boiler-hole top at the front and over the fire-chamber, and the two horizontally-swinging covers D D, pivoted to the top, each op erating independently of the other, to uncover a part of the fuel-supply aperture, and both to uncover the whole of it, and arranged in horizontal continuity with the top, as shown and described.

2. In a cooking'stove, the combination of the fuel-supply aperture A, formed in the top and at the front, and the two horizontallyswinging pivoted covers D D, the semicircular turn-plates H H, formed with the covers, the coinciding table-plates S, formed in the stove-top, the pivoting-apertures L, and the feathered pivot 1*, arranged to operate as and for the purposes herein described and set forth.
